ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients’ histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil’s Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.

RESUMO Objetivo: identificar a prevalência e os fatores associados ao diagnóstico tardio da infecção pelo vírus da imunodeficiência humana (HIV), em um município do interior paulista. Método: estudo epidemiológico, analítico e retrospectivo que analisou os casos de HIV e AIDS notificados pelos serviços de saúde no período de 2015 a 2017 por meio dos dados das notificações do Sistema de Informação de Agravos de Notificação (Sinan Net) dos usuários recém-diagnosticados para a infecção pelo HIV/AIDS no município de Ribeirão Preto/SP, Brasil. A coleta de dados ocorreu em maio de 2018. Foi realizado o teste qui-quadrado e regressão logística binária, no qual a variável dependente foi o critério de AIDS no momento da notificação da infecção pelo HIV. Foi considerado o valor de p<0,05 para a associação entre as variáveis estudadas com relação ao diagnóstico tardio. Resultados: dentre os 829 (100%) casos novos de HIV, 290 (35,0%) foram diagnosticados na condição de AIDS. A maioria da população pertencia ao sexo masculino e na faixa etária dos 15 aos 34 anos. A candidose oral e a perda de peso acima de 10% foram os principais sintomas associados à AIDS. Observou-se que pessoas com menor escolaridade e com o aumento da idade eram mais propensas a serem diagnosticadas tardiamente. Conclusão: estratégias que favoreçam o diagnóstico oportuno no município estudado são necessárias, particularmente entre os indivíduos com idade acima de 45 anos e com menor escolaridade.

ABSTRACT Objective: to identify the prevalence and factors associated with late diagnosis of the infection by the Human Immunodeficiency Virus (HIV), in a municipality of São Paulo. Method: an epidemiological, analytical and retrospective study that analyzed the HIV and AIDS cases notified by the health services in the period from 2015 to 2017 using data from the notifications of the Information System for Notifiable Diseases (SINAN Net) corresponding to the users recently diagnosed with HIV/AIDS infection in the municipality of Ribeirão Preto/SP, Brazil. Data collection was in May 2018. The chi-square test was performed, as well as binary logistic regression, where the dependent variable was the AIDS criterion at the moment of notifying infection by HIV. A p-value<0.05 was considered for the association between the variables studied in relation to late diagnosis. Results: of the 829 (100%) new HIV cases, 290 (35.0%) were diagnosed in the condition of AIDS. Most of the population was male and aged between 15 and 34 years old. Oral candidiasis and weight loss greater than 10% were the main symptoms associated with AIDS. It was observed that people with lower schooling levels and older were more prone to late diagnoses. Conclusion: it is necessary to devise strategies that favor timely diagnosis in the municipality under study, particularly among the individuals aged over 45 years old and with lower schooling levels.

Resumo: Analisamos o efeito do sexo, do estilo de elocução e da língua (alemão, estoniano, francês, inglês, italiano, português e sueco) sobre estimadores de tendência central e dispersão da frequência fundamental da fala. Os estilos são entrevista, leitura de frases e de palavras. As línguas diferem entre si em termos do valor típico de F0 usado por seus falantes. O estilo leitura de frases apresenta valores maiores do que a entrevista, mas o efeito não é uniforme entre as línguas. Diferenças significativas entre o estilo leitura de palavras e entrevista são mais raros. Todos os estimadores de tendência central estudados sofreram efeitos dos três fatores testados. Os homens apresentaram variabilidade de F0 ligeiramente maior do que as mulheres de forma significativa em três de cinco estimadores. O estilo entrevista tem maior variabilidade em dois. As línguas não diferem em termos de variabilidade de F0.

Abstract: We analyze the effect of speaker sex, speaking style and language (English, Estonian, French, German, Italian, Portuguese, Swedish) on global statistical measures of the voice fundamental frequency. The styles studied are interview, sentence reading and word list reading. Typical F0 values used by speakers among languages differ both in male and female speakers. Sentence reading has slightly higher values than interview, but the effect is not uniform among languages. In few cases word reading and interview values differ significantly. All central tendency estimators are affected by the variables tested. Three out of five estimators of dispersion show slightly higher values for male than for female speakers. Among styles, the interview has higher standard deviation and coefficient of variation. Languages do not differ among themselves in terms of F0 variability.

RESUMO Objetivo coletar normas de associação semântica de 96 palavras do português brasileiro e aplicá-las, posteriormente, na elaboração de um teste de reconhecimento de fala com frases com controle da previsibilidade da palavra. Método participaram 67 voluntários com idades entre 18 e 27 anos. Foi aplicada uma tarefa de associação semântica com delimitação de classe de palavras. Resultados o tamanho médio do conjunto total e do significativo foi maior para a segunda evocação para as classes de verbos e substantivos. A força de associação semântica que prevaleceu na primeira recordação foi forte para a primeira e média para a segunda palavra. Na segunda recordação, a força de associação com maior prevalência foi média para a primeira e para a segunda palavra. Foi observada correlação negativa significativa entre a força de associação e os tamanhos total e significativo do conjunto. Conclusão Normas de associação semântica de 96 palavras do português brasileiro foram coletadas conforme proposto e resultaram em palavras associadas semanticamente para cada alvo nas categorias de verbo e substantivo, as quais foram utilizadas em um teste de reconhecimento de fala com frases considerando a previsibilidade da palavra.

ABSTRACT Purpose To collect the semantic association norms of 96 Brazilian Portuguese words for further application in the formulation of a speech recognition test using sentences with controlled word predictability. Methods Study participants were 67 volunteers aged 18 to 27 years. A semantic association task with word class delimitation was used. Results The mean sizes of the total and meaning sets were larger in the second recall to both verb and noun classes. The prevalent semantic association strength in the first recall was strong to the first word and moderate to the second word. In the second recall, the prevalent semantic association strength was moderate to both the first and second words. Significant negative correlation was observed between association strength and total and meaning set sizes. Conclusion The semantic association norms of 96 Brazilian Portuguese words were collected as proposed and resulted in semantic associates for each target word in the verb and noun classes that were used in a speech recognition assessment considering sentences with controlled word predictability.

Abstract: En | Text: En | PDF: En

Climate change can be associated with variations in the frequency and intensity of extreme temperatures and precipitation events on the local and regional scales. Along coastal areas, flooding associated with increased occupation has seriously impacted products and services generated by marine life, in particular the biotechnological potential that macroalgae hold. Therefore, this paper analyzes the available information on the taxonomy, ecology and physiology of macroalgae and discusses the impacts of climate change and local stress on the biotechnological potential of Brazilian macroalgae. Based on data compiled from a series of floristic and ecological works, we note the disappearance in some Brazilian regions of major groups of biotechnological interest. In some cases, the introduction of exotic species has been documented, as well as expansion of the distribution range of economically important species. We also verify an increase in the similarities between the Brazilian phycogeographic provinces, although they still remain different. It is possible that these changes have resulted from the warming of South Atlantic water, as observed for its surface in southeastern Brazilian, mainly during the winter. However, unplanned urbanization of coastal areas can also produce similar biodiversity losses, which requires efforts to generate long-term temporal data on the composition, community structure and physiology of macroalgae.

OBJETIVO: Descrever o julgamento de concretude de um conjunto de 162 palavras da Língua Portuguesa, visando a elaboração de um teste de reconhecimento de fala, bem como verificar a influência de variáveis como frequência de ocorrência das palavras, idade e série do curso de graduação dos participantes neste julgamento. MÉTODOS: Cinquenta estudantes universitários de um curso de Fonoaudiologia de uma universidade pública julgaram 162 palavras quanto à concretude, por meio de uma escala de sete pontos, sendo o menor grau de concretude representado pelo número um e o grau de concretude máximo, representado pelo número sete. Foi permitido ao sujeito escolher qualquer ponto da escala. RESULTADOS: Os resultados mostraram uma distribuição tri-modal, sugerindo que as palavras fossem classificadas em três categorias quanto ao grau de concretude. A faixa de julgamento das palavras de baixa concretude variou de 1,76 a 3,45, as de média concretude, na faixa de 3,46 a 4,95 e as de alta concretude, de 4,96 e até 6,70. Houve correlação positiva entre o grau de concretude das palavras e o coeficiente de variação de forma que, quanto maior a nota atribuída para a palavra, menor foi a variação de respostas. Não ocorreu correlação significativa entre a frequência de ocorrência das palavras e o julgamento de concretude. A influência da idade e da série do curso de graduação no julgamento foi significativa para algumas correlações. CONCLUSÃO: Os resultados revelaram três categorias quanto ao grau de concretude e sugerem que a concretude pode ser considerada um atributo independente das palavras, uma vez que a frequência de ocorrência das palavras, bem como a idade e a série do curso de graduação dos participantes não influenciou o julgamento de concretude. As palavras categorizadas com alto grau de concretude foram utilizadas em etapas posteriores da elaboração de um teste de reconhecimento de fala.

PURPOSE: To describe the judgement of the concreteness of a set of 162 Brazilian Portuguese words, prior to the elaboration of a speech recognition test, as well as to verify the influence of variables such as the frequency of occurrence of the words and age and undergraduate program year of the participants on the concreteness ratings. METHODS: Fifty undergraduate Speech-Language Pathology and Audiology students from a public university rated the concreteness of a set of 162 words using a seven-point scale where the lowest concreteness degree was represented by number one and the highest by number seven. Participants were free to choose any number in the scale. RESULTS: The results showed a tri-modal distribution of values, suggesting the classification of three categories, according to the concreteness rating. The low concreteness category ranged from 1.76 to 3.45; the medium concreteness category, from 3.46 to 4.95; and the high concreteness rating, from 4.96 to 6.70. Positive correlation was found between the concreteness rating and the coefficient of variation, whereby the higher the rating attributed to a word, the lesser variation in the responses. No significant correlation was found between concreteness ratings and the frequency of occurrence of words. The influence of age and undergraduate year was significant for some correlations. CONCLUSION: Results showed three concreteness categories, and suggest that concreteness can be considered an independent attribute of words, since their frequency of occurrence, as well as participants' age and undergraduate program year did not influence the ratings attributed. The words classified in the high concreteness category were subsequently used for the elaboration of a speech recognition test.

Este artigo tem por objetivo apresentar as ações desenvolvidas na construção do modelo de atenção em saúde no Distrito Especial Indígena - Xingu (DSEI-Xingu), mais especificamente, na área de saúde bucal, com a efetiva parceria entre a Universidade Federal do Estado de São Paulo (UNIFESP), Faculdade de Odontologia de Ribeirão Preto - Universidade de São Paulo (FORP-USP) e a Colgate®, que permitiu a construção social da práxis em saúde no Médio e Baixo Xingu. Ao longo da história, o DSEI "Espaço Social" é onde as comunidades se constituem e, por meio do processo social de produção, cria acessos diferenciados aos bens de consumo, além de formar a base para a organização dos serviços de atenção à saúde dos povos indígenas. Para o DSEI-Xingu, são pontos básicos o estabelecimento de parcerias institucionais e a participação efetiva dos povos indígenas na gestão da saúde em seu território. Estruturado no planejamento baseado em problemas sentidos pela população, utiliza-se da construção coletiva de redes explicativas, apontando soluções em vários planos com abordagem intersetorial. É através da observação dos indicadores de saúde que se torna perceptível a assimilação das comunidades indígenas com o recente modelo de atenção básica à saúde bucal, uma vez que constantemente está sendo adaptado à cultura, à tradição e às singularidades desses povos indígenas.

The purpose of this article is to present the actions developed to create the health care model at the Special Indigenous District - Xingu (DSEI-Xingu); particularly regarding oral health. An effective partnership established among the following institutions University Federal of State São Paulo, University of São Paulo at Ribeirão Preto College of Dentistry and Colgate®, allowed the development of social health praxis at Middle and Low Xingu. The "Social Space" DSEI, which throughout the history, communities have developed and, through the social process of production, create differentiated accesses to consumer goods, is the basis for organizing health care services for the indigenous population. The DSEI-Xingu considers that establishing institutional partnerships as well as the effective participation of indigenous populations in health management in their territory is essential. Structured by plans based on population-reported problems, it uses the collective construction of explanatory networks, presenting solutions at different levels through an intersectorial approach. By observing health indicators, the indigenous communities' understanding of the recent primary health care model becomes perceptible, since it has been constantly applied to their culture, tradition, and uniqueness.

A colheita mecanizada de soja pode acarretar perdas qualitativas nas sementes. O presente trabalho teve como objetivo avaliar a qualidade de sementes de soja colhidas mecanicamente por sistemas axial e tangencial de trilha, em diferentes velocidades de avanço da colhedora, antes e após o período de armazenamento de seis meses. Utilizou-se o delineamento experimental de blocos casualizados, em esquema de parcela subdividida no tempo, com quatro repetições. Nas parcelas, foram avaliados os procedimentos de colheita e, nas subparcelas, as épocas de avaliação da qualidade da semente. Os procedimentos de colheita foram: colhedora com sistema de trilha axial, deslocando-se a 6, 8 e 10km h-1, colhedora com sistema de trilha tangencial (convencional), deslocando-se a 4 e 6km h-1, e colheita manual. Foram analisadas as seguintes variáveis: germinação, porcentagem de plântulas fortes, índice de velocidade de emergência (IVE), emergência em areia e injúria mecânica. Pôde-se concluir que o emprego das colhedoras com sistemas de trilha tangencial e axial não provocou diferenças no índice de velocidade de emergência, no vigor e na germinação das sementes de soja. No entanto, com relação à injúria mecânica, a colhedora axial mostrou-se superior à convencional. O incremento da velocidade de deslocamento, dentro dos parâmetros recomendados pelo fabricante, não alterou a qualidade das sementes. O armazenamento reduziu o vigor das sementes colhidas.

Soybean mechanical harvest may bring qualitative losses to seeds. This study aimed to evaluate the quality of soybean seeds mechanically harvested by axial and conventional threshing systems, at different displacement speeds of the harvesters, before and after the storage period of six months. A randomized complete block design in a split-plot arrangement with four replications was used. The main plots were the harvest systems and the split-plots were the storage times. The harvest systems were: axial flow harvester, at 6, 8 and 10km h-1, conventional harvester, at 4 and 6km h-1, and manual harvest. Germination, percentage of normal seedlings, emergency speed index, sand emergency and mechanical damage of soybean seeds were evaluated. The results showed that the use of axial flow and conventional harvesters did not affect the emergency speed index, vigor and germination of soybean seeds. However, the axial flow system provided less mechanical damage. The increase of displacement speed, within the ranges of the operating parameters recommended by the manufacturer, did not change seed quality. Storage reduced seed vigor.
